On DG2, a w/a resets RCS/CCS before it goes into RC6. This breaks OA since OA does not expect engine resets during its use. Fix it by disabling RC6. v2: (Ashutosh) - Bring back slpc_unset_param helper - Update commit msg - Use with_intel_runtime_pm helper for set/unset v3: (Ashutosh) - Just use intel_uc_uses_guc_rc Signed-off-by: Vinay Belgaumkar <vinay.belgaumkar@intel.com> Signed-off-by: Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com> Reviewed-by: Ashutosh Dixit <ashutosh.dixit@intel.com> Signed-off-by: John Harrison <John.C.Harrison@Intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221026222102.5526-15-umesh.nerlige.ramappa@intel.com
